What is the scheduling policy in the pthreads library?

The pthreads library allows for different scheduling policies, such as FIFO and Round Robin. These determine how threads are prioritized.

Can you explain the difference between FIFO and Round Robin scheduling?

Sure! FIFO (First In, First Out) processes threads in the order they arrive, while Round Robin allocates a fixed time slice to each thread in a cyclic order.

How do I set the scheduling policy for a thread in pthreads?

You can set the scheduling policy using the pthread_setschedparam function, specifying the thread, policy, and priority.

Are there any performance implications of using different scheduling policies?

Yes, different policies can affect performance based on the workload and system architecture. For example, FIFO may lead to starvation if high-priority threads dominate.
